Feat: headlamp integration

[Tatsinnit]

This work is headlamp integration into AKS VSC scenario using headlamps, in-cluster installation approach. (Opening this early as Draft)

Prima facie, we have utilized this enabling mechanism: https://headlamp.dev/docs/latest/installation/in-cluster/#using-simple-yaml

We just need to iron out the U/X but the main hook around this is already and leaving this open as Draft as advancement on what we have a align this for release in coming week or 2.

Thanks.

The unused reference to 'deployHeadlampInCluster' can be removed to clean up the code. Consider deleting it and its associated function if it is no longer required.
